Doorbell communication systems and methods

ABSTRACT

Doorbells can be used to detect visitors. Doorbells can have a field of view that includes a first portion and a second portion. Some embodiments include using a doorbell to detect a first object within the first portion of the field of view, and then determining if a doorbell button is pressed. If the doorbell button is not pressed, the doorbell may become less sensitive to objects detected in the first portion of the field of view. If the doorbell button is pressed, the doorbell may become more sensitive to objects detected in the first portion of the field of view. Multiple portions of the field of view may be independently adjusted based on doorbell button data.

BACKGROUND

1. Field

Various embodiments disclosed herein relate to doorbells. Certain embodiments relate to doorbell methods to detect visitors.

2. Description of Related Art

Doorbells can enable a person located outside of an entry point, such as a door, to alert a person inside of an entry point that someone outside would like to talk to someone inside. Doorbells sometimes include a button located near a door, such as a front door, side door, or back door of a home, office, dwelling, warehouse, building, or structure. Doorbells are sometimes used near a gate or some other entrance to a partially enclosed area. Pushing the doorbell sometimes causes a chime or other alerting sound to be emitted. In some cases, this alerting sound can typically be heard within a short distance from the entry point or sound source. For example, a homeowner located remotely from her home might not be able to hear the alerting sound, and thus, might not be aware that someone is ringing her doorbell. Thus, there is a need for devices and methods to alert remotely located individuals that someone seeks the attention of the homeowner, tenant, building guardian, or steward.

In some cases, doorbells should detect the presence of a visitor. Some doorbells, however, may falsely detect the presence of a visitor. Some doorbells may fail to detect a visitor. Thus, there is need for devices and methods that increase the accuracy and/or reliability of doorbells detecting visitors.

SUMMARY

Methods can include using a doorbell that is configurable to wirelessly communicate with a remotely located computing device, such as a cellular telephone, laptop, tablet, or desktop computer. Some embodiments include obtaining a doorbell that comprises a speaker, a microphone, a camera, and a button. In some embodiments, the camera acts as a motion sensor. A doorbell can include an infrared motion detection system. The button of the doorbell can be configurable to enable a visitor to sound a chime (e.g., a speaker or another sound emission device located inside a building). Some chimes are digital and others are mechanical.

Some embodiments include methods for using a doorbell system to detect a visitor. The doorbell system can comprise a doorbell and a remote computing device. Methods can include obtaining the doorbell system that comprises a visitor detection system. The visitor detection system can comprise at least one of a camera, a motion detector, and an infrared detector. The visitor detection system can be configured to detect a first indication suggestive of a first visitor.

An indication can be suggestive of the visitor if the indication is of a type that may indicate a visitor (even if the indication can sometimes result in false positives). For example, the indication can be a motion indication, but at times, motion indications may result from moving cars, pets, and plants. As a result, a motion indication may not actually indicate a visitor even though the indication suggests that a visitor may be present.

An infrared signature that seems to indicate that a visitor is present can be a type of indication. The infrared signature may be of a shape and/or temperature that suggests the infrared signature is from a visitor (i.e., a person). In many cases, infrared signatures suggestive of visitors are actually from visitors, but in some cases, infrared signatures suggestive of visitors may be misleading (and not actually be from visitors).

A shape in an image taken by a camera may be an indication suggestive of a visitor. For example, the shape can be of a size or geometry that suggests the shape represents at least a portion of a visitor. In some cases, shapes suggestive of a visitor may not actually be from a visitor.

Doorbell triggering (e.g., pressing) data can be used to substantiate suggestive indicators. Thus, embodiments can grow more skeptical of indicators if they are not followed by, for example, a visitor pressing the doorbell button. Certain areas of the field of view can be discounted or ignored altogether if indicators associated with the certain areas are not followed by a visitor pressing the doorbell button.

Embodiments can grow more confident of indicators if they are followed by a visitor pressing the doorbell button. In some embodiments, all areas of the field of view are configured to trigger an alert regarding the visitor until indications associated with certain areas are not followed by visitors pressing the button. Then, the system can ignore indications in those areas (to reduce the number of false positives).

Doorbells can comprise a button that is configurable to enable the first visitor to sound a chime. The chime can be located inside of the building to which the doorbell is attached. The chime can be digital or mechanical. In some embodiments, the chime can be a speaker attached to the building. Some users might not actually configure the doorbell button to sound a chime even though the button is configurable to sound the chime.

Several embodiments include configuring the doorbell system such that the visitor detection system comprises a field of view. The doorbell can include a camera, a motion sensor, and/or an infrared sensor that can be mounted in an entryway to enable the doorbell to see an area in front of the doorbell. In some embodiments, the camera, motion sensor, and/or infrared sensor is not physically coupled to the doorbell, but instead, is mounted remotely from the doorbell. The doorbell system can wirelessly communicate with the camera, motion sensor, and/or infrared sensor. In several embodiments, the camera, motion sensor, and/or infrared sensor is integrated into the doorbell.

Some embodiments include using the visitor detection system to detect the first indication suggestive of the first visitor within a first portion of the field of view and determining that the first indication detected within the first portion of the field of view is not associated with a triggering of the button.

Several methods can be used to determine if an indication is associated with a triggering of the button. In some embodiments, the system waits for a predetermined amount of time (e.g., 60 seconds or less) after detecting the indication to determine if the doorbell button is pressed. If the button is not pressed within the predetermined amount of time, then the indication is not associated with the triggering of the button.

The system can be configured to determine if the object that resulted in the indication suggestive of the visitor later pressed the doorbell button. For example, the system can detect an indication of an object (e.g., a car, a moving tree, a pet, a visitor). The system can then determine if the object later pressed the doorbell button.

If the object pressed the doorbell button, then the indication was associated with the triggering of the button. If the object did not press the doorbell button, then the object was not associated with the triggering of the button. This approach enables the system to calibrate its remote detection capabilities based on doorbell button data. Then, the system can more accurately determine if an indication is actually a visitor (to reduce false positives). As a result, the system can more reliably send an alert about a later visitor even if the visitor does not press the button.

A visitor can trigger the doorbell button in several ways. In many embodiments, the visitor triggers the doorbell button by pressing the doorbell button (e.g., to make the chime “ring”). Some embodiments include a button that can be triggered without pressing the button. For example, the visitor can trigger the button by touching the button. Some embodiments include “contactless” switches (e.g., Hall effect sensors) that enable triggering the button without actually touching the button.

Several embodiments include using the visitor detection system to detect a second indication suggestive of a second visitor within the first portion of the field of view and excluding the first portion of the field of view from causing an alert configured to notify the remote computing device regarding a presence of the second visitor. The excluding can be at least partially in response to determining that the first indication detected within the first portion of the field of view is not associated with the triggering of the button. The excluding prevents the second indication from causing the alert.

In some embodiments, this exclusion can create zones within the field of view that will not cause the system to send the alert even though the system detects an indication suggestive of a visitor in the excluded zones. This exclusion often will not prevent all indications from causing an alert if the indications are detected in non-excluded zones.

Several embodiments include using the visitor detection system to detect a third indication suggestive of the second visitor within a second portion of the field of view and then sending the alert in response to detecting the third indication within the second portion. The first indication can be a first motion indication, the second indication can be a second motion indication, and the third indication can be a third motion indication.

In some embodiments, the doorbell system determines that the first indication detected within the first portion of the field of view is not associated with the triggering of the button by determining that the button was not triggered within 60 seconds after detecting the first indication. 60 seconds can be a good timeframe because visitors approaching a doorbell will typically ring the doorbell within 60 seconds. If the item that caused the indication has not pressed the doorbell button within 60 seconds of being detected, then the item might not actually be a visitor and might be a passing car, a pet, a wind-blown tree branch, or another misleading item.

Of course, there will be times when an actual visitor does not press the doorbell button. For example, a person might choose to knock on the door instead of ringing the doorbell button. Thus, some embodiments include listening for sounds indicative of a visitor. Sounds indicative of a visitor include talking and knocking. Some embodiments are similar to other embodiments described herein except that the embodiments determine whether an indication detected within the first portion of the field of view is associated with sounds indicative of a visitor.

As a result of there being times when an actual visitor does not press the doorbell button, some embodiments do not immediately exclude a portion of the field of view from causing an alert, but instead, rely on data from many visitors and/or adjust the sensitivity of the visitor detector in the portion of the field of view.

In several embodiments, the visitor detection system comprises a camera, and using the visitor detection system to detect the first indication within the first portion of the field of view comprises using the camera to take a first image. Then, the doorbell system can analyze the first image to detect the first indication. Embodiments can include reducing a first sensitivity of the visitor detection system within the first portion in response to determining that the button was not triggered within a predetermined time after detecting the first indication and/or after taking the first image. Reducing the first sensitivity can reduce a first probability of causing a first alert configured to notify the remote computing device regarding a presence of a second visitor in response to detecting a second indication suggestive of the second visitor within the first portion of the field of view.

Some embodiments include using the camera to take a second image. Then, the doorbell system can analyze the second image to detect a third indication suggestive of a third visitor within a second portion of the field of view. Methods can include increasing a second sensitivity of the visitor detection system within the second portion in response to determining that the button was triggered within 60 seconds after detecting the third indication by analyzing the second image. Increasing the second sensitivity can increase a second probability of causing a second alert configured to notify the remote computing device regarding the presence of the third visitor in response to detecting the third indication within the second portion of the field of view.

Several embodiments include using a doorbell system to detect a first visitor. The doorbell system can comprise a doorbell and a remote computing device. Methods can include obtaining the doorbell that comprises a camera and a button. The button can be configurable to enable the first visitor to sound a chime. Methods can also include configuring the doorbell system such that the camera comprises a field of view; using the camera of the doorbell to take a baseline image to calibrate the doorbell system by establishing a baseline of at least a part of the field of view; using the camera of the doorbell to take a second image of at least the part of the field of view; determining that a first object is present in the second image, but not in the baseline image; associating the first object with a first portion of the field of view; determining that the button was not triggered within 60 seconds after determining that the first object is present in the second image, but not in the baseline image; and/or excluding the first portion of the field of view from causing an alert configured to notify the remote computing device regarding a presence of the first visitor. The excluding can be at least partially in response to determining that the button was not triggered within 60 seconds after detecting that the first object is present in the second image (but not in the baseline images).

Associating the first object with the first portion of the field of view can include correlating the first object with a location within the field of view. For example, the system can know where in the field of view the first object was detected. This relative location information can be helpful so the system can determine which areas of the field of view are causing misleading indications (e.g., as implied by an indication not being followed by a triggering of the doorbell button within 60 seconds of the system detecting the indication).

Many factors and methods can be used to exclude a portion of the field of view from causing an alert. For example, sound data and button data can be combined to exclude the portion of the field of view. In some embodiments, many button press data points are used to eventually exclude a portion of the field of view. Thus, excluding can be at least partially in response to determining that the button was not triggered within 60 seconds after determining that the first object is present in the second image, but not in the baseline image, even though other factors and methods are ultimately used in the full exclusion decision.

Several embodiments include using the camera of the doorbell to take a third image of at least the part of the field of view; determining that a second object is present in the third image, but not in the baseline image; associating the second object with a second portion of the field of view; determining that the button was triggered within 60 seconds after determining that the second object is present in the third image, but not in the baseline image; and/or configuring the doorbell system to automatically send the alert regarding a third object detected in the second portion of the field of view at least partially in response to determining that the button was triggered within 60 seconds after determining that the second object is present in the third image, but not in the baseline image.

Some embodiments include using the camera of the doorbell to take a fourth image of at least the part of the field of view; determining that the third object is present in the fourth image, but not in the baseline image; associating the third object with the second portion of the field of view; and/or automatically sending the alert to the remote computing device regarding the presence of a visitor.

Several embodiments include automatically initiating the sending of the alert to the remote computing device regarding the presence of the first visitor prior to the first visitor pressing the button. Initiating the sending of the alert does not necessarily mean that the alert has arrived at the remote computing device.

The baseline image can comprise several images. In some embodiments, the baseline image is actually a collection of images taken at different times. Thus, a first image can be the baseline image for a second image, and the second image can be the baseline image for a third image.

In some embodiments, the visitor detection system comprises a motion detector. Using the visitor detection system to detect the first indication within the first portion of the field of view can comprise detecting a first motion within the first portion. Embodiments can include reducing a first sensitivity of the visitor detection system within the first portion in response to determining that the button was not triggered within a predetermined time (e.g., 60 seconds, 30 seconds, 15 seconds) after detecting the first indication. Reducing the first sensitivity can reduce a first probability of causing an alert configured to notify the remote computing device regarding a presence of a second visitor in response to detecting a second indication suggestive of the second visitor within the first portion of the field of view.

Several embodiments include using the visitor detection system to detect a second motion within a second portion of the field of view; and/or increasing a second sensitivity of the visitor detection system within the second portion in response to determining that the button was triggered within 60 seconds after detecting the second motion. Increasing the second sensitivity can increase a second probability of causing the alert configured to notify the remote computing device regarding the presence of the second visitor in response to detecting the second motion within the second portion of the field of view.

Some embodiments include dividing the field of view into the first portion and the second portion such that the doorbell system is configured to distinguish between the first motion detected in the first portion and the second motion detected in the second portion. A wall (e.g., a plastic blade) can be used to divide the field of view. In some embodiments, the field of view is divided with software (e.g., rather than being physically divided by a wall).

Several embodiments for using a doorbell to detect visitors include obtaining the doorbell system that comprises a motion detector and a button; configuring the doorbell system such that the motion detector comprises a field of view; detecting a first motion within a first portion of the field of view; determining that the button was not triggered within 60 seconds after detecting the first motion within the first portion of the field of view; and/or excluding the first portion of the field of view from causing an alert configured to notify the remote computing device regarding a presence of the first visitor. The excluding can be at least partially in response to determining that the button was not triggered within 60 seconds after detecting the first motion within the first portion of the field of view.

Some embodiments include detecting a second motion within a second portion of the field of view; determining that the button was triggered within 60 seconds after detecting the second motion within the second portion of the field of view; and/or configuring the doorbell system to automatically send the alert regarding a third motion detected in the second portion of the field of view at least partially in response to determining that the button was triggered within 60 seconds after detecting the second motion within the second portion of the field of view.

Several embodiments include detecting the third motion within the second portion of the field of view; and/or automatically sending the alert to the remote computing device regarding the presence of the first visitor in response to detecting the third motion within the second portion of the field of view. Methods can include automatically initiating the sending of the alert to the remote computing device regarding the presence of the first visitor prior to the first visitor pressing the button.

Speed is one factor that can help distinguish between misleading motion and motion that is from an actual visitor. People tend to approach doorbells at less than 5 miles per hour. In contrast, cars tend to drive over 25 miles per hour and often drive over 35 miles per hour. Excluding motion that is over 5 miles per hour can help improve the accuracy of the doorbell system (by screening out motions that are too fast to likely be from a visitor).

Several methods include detecting a speed of the first motion; and/or excluding the first motion from causing the alert configured to notify the remote computing device regarding the presence of the first visitor. The excluding can be at least partially in response to the speed being greater than a predetermined threshold. The predetermined threshold can be at least 5 miles per hour and can be less than 35 miles per hour. A predetermined threshold of 15 miles per hour provides a very reliable dividing line between people walking up to a doorbell and cars driving in front of the doorbell. Several embodiments include a predetermined threshold of at least 15 miles per hour.

In some embodiments, the visitor detection system comprises the infrared detector, wherein using the visitor detection system to detect the first indication within the first portion of the field of view comprises detecting a first infrared signature within the first portion. Methods can include reducing a first sensitivity of the visitor detection system within the first portion in response to determining that the button was not triggered within 60 seconds after detecting the first indication. Reducing the first sensitivity can reduce a first probability of causing a first alert configured to notify the remote computing device regarding a presence of a second visitor in response to detecting a second indication suggestive of the second visitor within the first portion of the field of view.

In several embodiments, the infrared detector comprises a first infrared sensor and a second infrared sensor. The doorbell can comprise a wall that separates the first infrared sensor from the second infrared sensor such that the first infrared sensor is configured to detect the first infrared signature within the first portion and the second infrared sensor is configured to detect a second infrared signature within a second portion of the field of view.

Some embodiments include using the infrared detector to detect a third indication suggestive of a third visitor within a second portion of the field of view; and/or increasing a second sensitivity of the visitor detection system within the second portion in response to determining that the button was triggered within 60 seconds after detecting the third indication. Increasing the second sensitivity can increase a second probability of causing a second alert configured to notify the remote computing device regarding the presence of the third visitor in response to detecting the third indication within the second portion of the field of view.

Several embodiments include using a doorbell system to detect a first visitor. The doorbell system can comprise a doorbell and a remote computing device. Methods can include obtaining the doorbell that comprises a field of view having at least a first portion and a second portion. The doorbell can comprise a button that is configurable to enable the first visitor to sound a chime. Embodiments can include using doorbell to detect a first object within the first portion of the field of view; and/or determining that the button was not pressed within a predetermined time after the doorbell detects the first object within the first portion of the field of view. Embodiments can include excluding the first portion of the field of view from causing an alert configured to notify the remote computing device regarding a presence of the first visitor. The excluding can be at least partially in response to determining that the button was not triggered within 60 seconds after the doorbell detects the first object within the first portion of the field of view.

Embodiments can include using the doorbell to detect a second object within the second portion of the field of view; and/or sending the alert to the remote computing device in response to the doorbell detecting the second object within the second portion of the field of view.

Several embodiments include using a doorbell system to detect a first visitor. The doorbell system can comprise a doorbell and a remote computing device such as a smartphone, laptop, tablet, or desktop computer. Some embodiments include obtaining the doorbell that comprises a camera, a speaker, a microphone, and a button, wherein the button is configurable to enable the first visitor to sound a chime. Methods can include configuring the camera of the doorbell such that the camera comprises a field of view, and using the camera of the doorbell to take a first image. The doorbell system can send the first image from the doorbell to the remote computing device, which can comprise an electronic display (e.g., a computer screen). Some methods include displaying the first image on the electronic display of the remote computing device and prompting a user of the remote computing device to select a first detection zone within the first image. The first detection zone can comprise a portion of the first image.

Some embodiments include using the camera of the doorbell to take a second image, analyzing the second image to detect a first indication of the first visitor, and determining that the first indication of the first visitor in the second image is located outside of the first detection zone. The doorbell system can then decide not to send an alert to the remote computing device in response to determining that the first indication of the first visitor in the second image is located outside of the first detection zone. The alert can be configured to notify the remote computing device regarding a presence of the first visitor.

Analyzing the second image can include determining if there are signs of seeing the visitor in the second image. In some embodiments, the system looks for indications of motion in the image. In several embodiments, the system compares a baseline image (e.g., the first image) to the second image in order to determine if there are areas in the second image that include an object (e.g., a visitor) that was not present in the first image. Thus, some embodiments use computer vision to identify the presence of a visitor within the detection zone.

Several embodiments include using the camera of the doorbell to take a third image, and analyzing the third image to detect a second indication of the first visitor. Methods can include determining that the second indication of the first visitor in the third image is located inside of the first detection zone, and then sending the alert to the remote computing device in response to determining that the second indication of the first visitor in the third image is located inside of the first detection zone. In some embodiments, the alert is not sent unless other conditions are met.

Some embodiments include displaying a grid pattern on the first image on the electronic display of the remote computing device such that the first image is divided into at least ten sections by lines that cross each other. The lines can include horizontal and vertical lines that intersect at 90 degree angles. The lines can be straight, curved, and/or wavy. The sections can be equal in size and shape. The sections can be irregular and can vary in size. Methods can include preventing the sending of the alert to the remote computing device until after detecting an indication of a visitor in at least two, four, and/or eight of the sections. Methods can include preventing the sending of the alert to the remote computing device until after detecting an indication of a visitor in at least twenty percent and/or forty percent of the sections.

Several methods include selecting the first detection zone within the first image by the user touching at least a first subset of the sections on the electronic display of the remote computing device. Touching the first subset causes the first subset to be included in the first detection zone. The electronic display can be a touchscreen of a computer such as a smartphone or tablet. The user of the remote computing device can swipe the touchscreen to select a detection zone. Touching or clicking on each section is not necessary in some embodiments.

Some methods include causing a second subset of the sections to be included in the first detection zone in response to the first subset comprising an outer perimeter that surrounds the second subset. For example, the user can swipe the touchscreen to form a closed shape. All sections at least partially located within the closed shape can be included in the first detection zone.

Some embodiments include two, three, four, and/or many detection zones, which can be independent, interdependent, separate, and/or overlapping. Detecting a visitor in a first detection zone can lead to immediately notifying the user of the remote computing device. Detecting a visitor in a second detection zone can include additional safeguards against false-positives.

Several embodiments include selecting the first detection zone by displaying the first image on the electronic display and then recording which areas of the first image the user indicates to include in the first detection zone by touching the electronic display. Some methods include calculating a percentage of the first detection zone that includes the second indication of the first visitor. The percentage can be a percentage of the area of the detection zone or can be a percentage of the sections. Methods can include sending the alert to the remote computing device in response to determining that the percentage of the detection zone exceeds a first threshold. The first threshold can be 10 percent or 30 percent.

Some methods include sending a picture of a visitor to the remote computing device, and then waiting to open audio and/or video communication between the visitor and the user of the remote computing device until after determining a percentage of the first detection zone that includes an indication of the third visitor and calculating a time in which the indication of the third visitor has been in the first detection zone. Embodiments can include opening the audio communication between the third visitor and the user of the remote computing device in response to the percentage of the detection zone and the time. The percentage can be at least 10 percent and/or at least 25 percent. The time can be at least one second and/or at least four seconds.

Indications of the visitor can be motion indications. Motion indications can be identified by comparing a baseline image to another image. The baseline image can be taken when a visitor is not present. Other indications of the visitor can include presence indications (e.g., indications that at least a portion of the visitor is present in the section being analyzed).

Some embodiments include selecting the first detection zone by displaying the first image on the electronic display and then recording which areas of the first image the user indicates to include in the first detection zone by touching the electronic display. The remote computing device can prompt the user to select areas and/or sections to include in a detection zone. In some embodiments, the remote computing device does not display a grid on the calibration image, but the remote computing device prompts the user to select a portion of the image as the detection zone and/or prompts the user to select a portion of the image to exclude from the detection zone.

Several embodiments include calculating a percentage of the first detection zone that includes the second indication of the first visitor and/or calculating a time in which the second indication of the first visitor has been in the first detection zone. Methods can include sending the alert to the remote computing device in response to the percentage of the detection zone and the time.

The images used in several methods do not necessarily include the entire field of view of the camera of the doorbell. In some embodiments, the field of view comprises a portion, and the first image, the second image, and the third image consist of the portion of the field of view. Methods can further comprise selecting the portion of the field of view. In some embodiments, the images include the entire field of view of the camera.

The portion of the field of view can be consistent between the calibration image and subsequent images to help the system accurately analyze the images. In some methods, the first image, the second image, and the third image consist of at least a portion of the field of view, wherein the method further comprises analyzing the portion of the field of view.

Although doorbells can be used anywhere, in some embodiments, the camera of the doorbell is configured to record a portion of an entryway, wherein the first image, the second image, and the third image show the portion of the entryway.

In some embodiments, the doorbell and the remote computing device are not physically coupled. Methods can include wirelessly sending the first image from the doorbell to the remotely located computing device. Some embodiments include sending the first image directly from the doorbell to the remote computing device without an intermediary server. This direct transmission can be via wires or can be wireless. Several embodiments include intermediary servers that enable the doorbell to communicate with the remote computing device via the Internet.

Methods for using a doorbell system to detect a first visitor can include obtaining the doorbell that comprises a camera and a button. The camera can be configured such that the camera has a field of view. Several embodiments include using the camera of the doorbell to take a first image to calibrate the doorbell system and sending the first image from the doorbell to the remote computing device. Some methods include displaying the first image on the electronic display of the remote computing device. Several embodiments include prompting a user of the remote computing device to select a first detection zone within the first image. The first detection zone can comprise at least a portion of the first image. Methods can include configuring the doorbell system to ignore a second visitor located within the field of view but located outside of the first detection zone. Ignoring the second visitor can include failing to send a notification regarding the second visitor to the remote computing device (e.g., even if the doorbell otherwise responds to the second visitor, for example, by flashing an LED light).

The system can ignore a visitor by not sending an alert regarding the visitor to the remote computing device. In some embodiments, the system does not send an alert to the remote computing device in response to the presence of the visitor outside the detection zone but inside the field of view of the camera and/or inside the image. Even when the system ignores a visitor, the system can record the visitor for future reference by the user. The user can then request to see visitors who were inside the field of view but not shown via alerts (because they were ignored due to being located outside the detection zone). Thus, the system can ignore the visitor in response to the presence of the visitor outside the detection zone, but the system can later provide information regarding the visitor to the user in response to a user's request. Sending an alert can include sending a push notification to a smartphone.

Several methods include configuring the doorbell system to send a picture of a third visitor to the remote computing device in response to determining that the third visitor is located inside of the first detection zone as defined based on the first image. The first detection zone can be a two-dimensional zone rather than a three-dimensional area of the physical world. Thus, the detection zone can be decoupled from proximity.

Some method embodiments include enabling audio and/or video communication between a visitor and the user of the remote computing device in response to detecting at least one indication of the visitor in at least two of the sections and/or in at least ten of the sections. In some embodiments, the sections with the detected indications must be adjacent to each other.

Some embodiments include selecting the first detection zone within the first image by prompting the user of the remote computing device to indicate a first area by touching the first area on the electronic display of the remote computing device; recording the first area; and excluding the first area from the first detection zone. Methods can include ignoring a visitor in response to the visitor being located in the first area. The user can select areas for exclusion from the detection zone and can select areas for inclusion in the detection zone.

Doorbells can comprise a motion sensor. Some embodiments include an infrared motion sensor. Methods can comprise ignoring the second visitor in response to disabling the motion sensor during a predetermined time period. The predetermined time period can be during certain hours of the day or night. The time period can be when the user is home or away from home (e.g., where the doorbell is mechanically coupled to the home). As used herein, “home” can include any type of stationary structure configured to shelter people (e.g., an office building).

Several embodiments include using a doorbell system to detect at least one visitor. Methods can include configuring the camera of the doorbell such that the camera comprises a field of view and using the camera of the doorbell to take a first image to calibrate the doorbell system by establishing a baseline of an entryway. The baseline can be used to define a state without any visitors. Methods can include sending the first image from the doorbell to the remote computing device and displaying the first image on an electronic display of the remote computing device.

Some methods include prompting a user of the remote computing device to select a first detection zone within the first image. The first detection zone can comprise a portion of the first image. The first detection zone can include a two-dimensional representation of an area in which the doorbell system is configured to respond to motion detection. Several embodiments include displaying a grid pattern on the first image on the electronic display of the remote computing device such that the first image is divided into at least six sections by lines that cross each other. The system can be configured to identify the first detection zone within the first image by the user choosing at least a first subset of the sections on the electronic display of the remote computing device. Choosing the first subset can cause the first subset to be included in the first detection zone.

Several methods include configuring the doorbell system to ignore a second visitor located within the field of view but located outside of the first detection zone. Some embodiments include configuring the doorbell system to send a picture of a third visitor to the remote computing device in response to at least some of the following factors: (1) determining that the third visitor is located inside of the first detection zone as defined based on the first image, (2) determining that at least a predetermined percentage (e.g., thirty percent) of the first detection zone includes motion or visitors indicators, and (3) determining that the first detection zone has included the indicators for at least a predetermined amount of time (e.g., three seconds).

Some methods include automatically excluding an area from a detection zone. Automatic exclusion can occur without the user excluding a specific area (even if the user configures settings that later lead to automatic exclusions). In some embodiments, indications indicative of motorized vehicles (e.g., cars, trucks, vans) are automatically excluded from a detection zone. These automatic calibration innovations can take many forms. Several methods include automatically excluding an area from a detection zone in response to detecting an object (e.g., a motorized vehicle) moving through the first detection zone at more than twenty-five miles per hour. Some methods include automatically excluding an area in response to detecting an infrared signal indicative of a motorized vehicle.

Some embodiments include automatically excluding an area from the first detection zone in response to at least some of the following items: (1) detecting an indication of a visitor in a detection zone; (2) enabling audio communication between the doorbell and the remote computing device in response to detecting the indication of the visitor; and (3) using the doorbell to detect an absence of sound indicative of speaking. The area that is excluded can be the area in which the indication was detected.

Thus, the scope of the claims appended hereto is not limited by any of the particular embodiments described below. For example, in any method or process disclosed herein, the acts or operations of the method or process may be performed in any suitable sequence and are not necessarily limited to any particular disclosed sequence. Various operations may be described as multiple discrete operations in turn, in a manner that may be helpful in understanding certain embodiments; however, the order of description should not be construed to imply that these operations are order dependent. Additionally, the structures, systems, and/or devices described herein may be embodied as integrated components or as separate components.

For purposes of comparing various embodiments, certain aspects and advantages of these embodiments are described. Not necessarily all such aspects or advantages are achieved by any particular embodiment. Thus, for example, various embodiments may be carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other aspects or advantages as may also be taught or suggested herein.

Doorbell systems can include a doorbell, a remote computing device, and a means of communication between the doorbell and the remote computing device. The means of communication can include the Internet, a wireless network, and/or a server. In some embodiments, the doorbell communicates with the remote computing device without using a server.

Doorbells can include a means of visitor detection. For example, the doorbell can use a motion sensor. In some embodiments, the camera of the doorbell can be used to detect visitors by comparing a baseline image to a second image taken when the visitor is present.

False positives can be problematic. Thus, some embodiments include defining at least one detection zone within the field of view (FOV) of the camera. The doorbell system can be configured such that areas outside of the detection zones will not trigger sending a notification to a user of a remote computing device.

The detection zones can be created using many different methods. In some methods, a picture taken by the camera of the doorbell is displayed on the remote computing device. The picture is divided into sections by a grid. The user can select which areas of the grid should be included in the detection zones.

FIG. 1 illustrates a security system 202 (e.g., a doorbell) that includes a camera assembly 208 and a motion detector 218. When a visitor approaches the security system 202 (e.g., rings a doorbell button 212), the security system 202 can send a wireless notification to a computing device 204 that is located remotely relative to the security system 202.

System Embodiments

Communication systems can provide a secure and convenient way for a remotely located individual to communicate with a person who is approaching a sensor, such as a proximity sensor or motion sensor, or with a person who rings a doorbell, which can be located in a doorway, near an entrance, or within 15 feet of a door. Some communication systems allow an individual to hear, see, and talk with visitors who approach at least a portion of the communication system and/or press a button, such as a doorbell's button. For example, communication systems can use a computing device to enable a remotely located person to see, hear, and/or talk with visitors. Computing devices can include computers, laptops, tablets, mobile devices, smartphones, cellular phones, and wireless devices (e.g., cars with wireless communication). Example computing devices include the iPhone, iPad, iMac, MacBook Air, and MacBook Pro made by Apple Inc. Communication between a remotely located person and a visitor can occur via the Internet, cellular networks, telecommunication networks, and wireless networks.

Referring now to FIG. 1, communication systems can be a portion of a smart home hub. In some embodiments, the communication system 200 forms the core of the smart home hub. For example, the various systems described herein enable complete home automation. In some embodiments, the security system 202 controls various electrical items in a home (e.g., lights, air conditioners, heaters, motion sensors, garage door openers, locks, televisions, computers, entertainment systems, pool monitors, elderly monitors). In some embodiments, the computing device 204 controls the security system 202 and other electrical items in a home (e.g., lights, air conditioners, heaters, motion sensors, garage door openers, locks, televisions, computers, entertainment systems, pool monitors, elderly monitors).

FIG. 1 illustrates a front view of a communication system embodiment. The communication system 200 can include a security system 202 (e.g., a doorbell) and a computing device 204. Although the illustrated security system 202 includes many components in one housing, several security system embodiments include components in separate housings. The security system 202 can include a camera assembly 208 and a doorbell button 212. The camera assembly 208 can include a video camera, which in some embodiments is a webcam. The security system 202 can include a diagnostic light 216 and a power indicator light 220. In some embodiments, the diagnostic light 216 is a first color (e.g., blue) if the security system 202 and/or the communication system 200 is connected to a wireless Internet network and is a second color (e.g., red) if the security system 202 and/or the communication system 200 is not connected to a wireless Internet network. In some embodiments, the power indicator 220 is a first color if the security system 202 is connected to a power source. The power source can be power supplied by the building to which the security system 202 is attached. In some embodiments, the power indicator 220 is a second color or does not emit light if the security system 202 is not connected to the power source.

The security system 202 (e.g., a doorbell) can include an outer housing 224, which can be water resistant and/or waterproof. The outer housing can be made from metal or plastic, such as molded plastic with a hardness of 60 Shore D. In some embodiments, the outer housing 224 is made from brushed nickel or aluminum.

Rubber seals can be used to make the outer housing 224 water resistant or waterproof. The security system 202 can be electrically coupled to a power source, such as wires electrically connected to a building's electrical power system. In some embodiments, the security system 202 includes a battery for backup and/or primary power.

Wireless communication 230 can enable the security system 202 (e.g., a doorbell) to communicate with the computing device 204. Some embodiments enable communication via cellular and/or WiFi networks. Some embodiments enable communication via the Internet. Several embodiments enable wired communication between the security system 202 and the computing device 204. The wireless communication 230 can include the following communication means: radio, WiFi (e.g., wireless local area network), cellular, Internet, Bluetooth, telecommunication, electromagnetic, infrared, light, sonic, and microwave. Other communication means are used by some embodiments. In some embodiments, such as embodiments that include telecommunication or cellular communication means, the security system 202 can initiate voice calls or send text messages to a computing device 204 (e.g., a smartphone, a desktop computer, a tablet computer, a laptop computer).

Several embodiments use near field communication (NFC) to communicate between the computing device 204 and the security system 202; between the security system 202 and the door lock 250; and/or between the computing device 204 and the door lock 250. The security system 208, the computing device 204, and/or the door lock 250 can include a NFC tag. Some NFC technologies include Bluetooth, radio-frequency identification, and QR codes.

Some embodiments include computer software (e.g., application software), which can be a mobile application designed to run on smartphones, tablet computers, and other mobile devices. Software of this nature is sometimes referred to as “app” software. Some embodiments include software designed to run on desktop computers and laptop computers.

The computing device 204 can run software with a graphical user interface. The user interface can include icons or buttons. In some embodiments, the software is configured for use with a touch-screen computing device such as a smartphone or tablet.

FIG. 2 illustrates a computing device 204 running software. The software includes a user interface 240 displayed on a display screen 242. The user interface 240 can include a security system indicator 244, which can indicate the location of the security system that the user interface is displaying. For example, a person can use one computing device 204 to control and/or interact with multiple security systems, such as one security system located at a front door and another security system located at a back door. Selecting the security system indicator 244 can allow the user to choose another security system (e.g., the back door security system rather than the front door security system).

The user interface 240 can include a connectivity indicator 248. In some embodiments, the connectivity indicator can indicate whether the computing device is in communication with a security system, the Internet, and/or a cellular network. The connectivity indicator 248 can alert the user if the computing device 204 has lost its connection with the security system 202; the security system 202 has been damaged; the security system 202 has been stolen; the security system 202 has been removed from its mounting location; the security system 202 lost electrical power; and/or if the computing device 204 cannot communicate with the security system 202. In some embodiments, the connectivity indicator 248 alerts the user of the computing device 204 by flashing, emitting a sound, displaying a message, and/or displaying a symbol.

In some embodiments, if the security system 202 loses power, loses connectivity to the computing device 204, loses connectivity to the Internet, and/or loses connectivity to a remote server, a remote server 206 sends an alert (e.g., phone call, text message, image on the user interface 240) regarding the power and/or connectivity issue. In several embodiments, the remote server 206 can manage communication between the security system 202 and the computing device. In some embodiments, information from the security system 202 is stored by the remote server 206. In several embodiments, information from the security system 202 is stored by the remote server 206 until the information can be sent to the computing device 204, uploaded to the computing device 204, and/or displayed to the remotely located person via the computing device 204. The remote server 206 can be a computing device that stores information from the security system 202 and/or from the computing device 204. In some embodiments, the remote server 206 is located in a data center.

In some embodiments, the computing device 204 and/or the remote server 206 attempts to communicate with the security system 202. If the computing device 204 and/or the remote server 206 is unable to communicate with the security system 202, the computing device 204 and/or the remote server 206 alerts the remotely located person via the software, phone, text, a displayed message, and/or a website. In some embodiments, the computing device 204 and/or the remote server 206 attempts to communicate with the security system 202 periodically; at least every five hours and/or less than every 10 minutes; at least every 24 hours and/or less than every 60 minutes; or at least every hour and/or less than every second.

In some embodiments, the server 206 can initiate communication to the computer device 204 and/or to the security system 202. In several embodiments, the server 206 can initiate, control, and/or block communication between the computing device 204 and the security system 202.

In several embodiments, a user can log into an “app,” website, and/or software on a computing device (e.g., mobile computing device, smartphone, tablet, desktop computer) to adjust the security system settings discussed herein.

In some embodiments, a computing device can enable a user to watch live video and/or hear live audio from a security system due to the user's request rather than due to actions of a visitor. Some embodiments include a computing device initiating a live video feed (or a video feed that is less than five minutes old).

In some embodiments, the user interface 240 displays an image 252 such as a still image or a video of an area near and/or in front of the security system 202. The image 252 can be taken by the camera assembly 208 and stored by the security system 202, server 206, and/or computing device 204. The user interface 240 can include a recording button 256 to enable a user to record images, videos, and/or sound from the camera assembly 208, microphone of the security system 202, and/or microphone of the computing device 204.

In several embodiments, the user interface 240 includes a picture button 260 to allow the user to take still pictures and/or videos of the area near and/or in front of the security system 202. The user interface 240 can also include a sound adjustment button 264 and a mute button 268. The user interface 240 can include camera manipulation buttons such as zoom, pan, and light adjustment buttons. In some embodiments, the camera assembly 208 automatically adjusts between Day Mode and Night Mode. Some embodiments include an infrared camera and/or infrared lights to illuminate an area near the security system 202 to enable the camera assembly 208 to provide sufficient visibility (even at night).

In some embodiments, buttons include diverse means of selecting various options, features, and functions. Buttons can be selected by mouse clicks, keyboard commands, and touching a touch screen. Many embodiments include buttons that can be selected without touch screens.

In some embodiments, the user interface 240 includes a quality selection button, which can allow a user to select the quality and/or amount of the data transmitted from the security system 202 to the computing device 204 and/or from the computing device 204 to the security system 202.

In some embodiments, video can be sent to and/or received from the computing device 204 using video chat protocols such as FaceTime (by Apple Inc.) or Skype (by Microsoft Corporation). In some embodiments, these videos are played by videoconferencing apps on the computing device 204 instead of being played by the user interface 240.

The user interface 240 can include a termination button 276 to end communication between the security system 202 and the computing device 204. In some embodiments, the termination button 276 ends the ability of the person located near the security system 202 (i.e., the visitor) to hear and/or see the user of the computing device 204, but does not end the ability of the user of the computing device 204 to hear and/or see the person located near the security system 202.

In some embodiments, a button 276 is both an answer button (to accept a communication request from a visitor) and is a termination button (to end communication between the security system 202 and the computing device 204). The button 276 can include the word “Answer” when the system is attempting to establish two-way communication between the visitor and the user. Selecting the button 276 when the system is attempting to establish two-way communication between the visitor and the user can start two-way communication. The button 276 can include the words “End Call” during two-way communication between the visitor and the user. Selecting the button 276 during two-way communication between the visitor and the user can terminate two-way communication. In some embodiments, terminating two-way communication still enables the user to see and hear the visitor. In some embodiments, terminating two-way communication causes the computing device 204 to stop showing video from the security system and to stop emitting sounds recorded by the security system.

In some embodiments, the user interface 240 opens as soon as the security system detects a visitor (e.g., senses indications of a visitor). Once the user interface 240 opens, the user can see and/or hear the visitor even before “answering” or otherwise accepting two-way communication, in several embodiments.

Some method embodiments include detecting a visitor with a security system. The methods can include causing the user interface to display on a remote computing device 204 due to the detection of the visitor (e.g., with or without user interaction). The methods can include displaying video from the security system and/or audio from the security system before the user accepts two-way communication with the visitor. The methods can include displaying video from the security system and/or audio from the security system before the user accepts the visitor's communication request. The methods can include the computing device simultaneously asking the user if the user wants to accept (e.g., answer) the communication request and displaying audio and/or video of the visitor. For example, in some embodiments, the user can see and hear the visitor via the security system before opening a means of two-way communication with the visitor.

In some embodiments, the software includes means to start the video feed on demand. For example, a user of the computing device might wonder what is happening near the security system 202. The user can open the software application on the computing device 204 and instruct the application to show live video and/or audio from the security device 202 even if no event near the security system 202 has triggered the communication.

In several embodiments, the security device 202 can be configured to record when the security device 202 detects movement and/or the presence of a person. The user of the computing device 204 can later review all video and/or audio records when the security device 202 detected movement and/or the presence of a person.

Referring now to FIG. 1, in some embodiments, the server 206 controls communication between the computing device 204 and the security system 202, which can be a doorbell with a camera, a microphone, and a speaker. In several embodiments, the server 206 does not control communication between the computing device 204 and the security system 202.

In some embodiments, data captured by the security system and/or the computing device 204 (such as videos, pictures, and audio) is stored by another remote device such as the server 206. Cloud storage, enterprise storage, and/or networked enterprise storage can be used to store video, pictures, and/or audio from the communication system 200 or from any part of the communication system 200. The user can download and/or stream stored data and/or storage video, pictures, and/or audio. For example, a user can record visitors for a year and then later can review conversations with visitors from the last year. In some embodiments, remote storage, the server 206, the computing device 204, and/or the security system 202 can store information and statistics regarding visitors and usage.

FIG. 3 illustrates an embodiment in which a security system 202 is connected to a building 300, which can include an entryway 310 that has a door 254. A door lock 250 can be configured to lock and unlock the door 254. Electrical wires 304 can electrically couple the security system 202 to the electrical system of the building 300 such that the security system 202 can receive electrical power from the building 300.

A wireless network 308 can allow devices to wirelessly access the Internet. The security system 202 can access the Internet via the wireless network 308. The wireless network 308 can transmit data from the security system 202 to the Internet, which can transmit the data to remotely located computing devices 204. The Internet and wireless networks can transmit data from remotely located computing devices 204 to the security system 202. In some embodiments, a security system 202 connects to a home's WiFi.

As illustrated in FIG. 3, one computing device 204 (e.g., a laptop, a smartphone, a mobile computing device, a television) can communicate with multiple security systems 202. In some embodiments, multiple computing devices 204 can communicate with one security system 202.

In some embodiments, the security system 202 can communicate (e.g., wirelessly 230) with a television 306, which can be a smart television. Users can view the television 306 to see a visitor and/or talk with the visitor.

As used herein, an “electronic device” is capable of displaying images, including videos. An electronic device consumes electrical power and is capable of running software. As used herein, the term “electronic device” should not be confused with the term “electronic key.” Many electronic key embodiments are not capable of displaying images, consuming electrical power, or running software.

Visitor Detection

Referring now to FIGS. 1 and 3, methods can include using a doorbell (e.g., security system 202) that is configurable to wirelessly communicate with a remotely located computing device 204, such as a cellular telephone, laptop, or tablet. Some embodiments include obtaining a doorbell that comprises a speaker, a microphone, a camera, and a button. In some embodiments, the camera acts as a motion sensor. A doorbell can include an infrared motion detection system (e.g., motion detector 218). The button 212 of the doorbell can be configurable to enable a visitor to sound a chime 302 (e.g., a speaker or another sound emission device located inside of a building). Some chimes are digital and some chimes are mechanical.

Several embodiments include using a doorbell system (e.g., communication system 200) to detect a first visitor. The doorbell system can comprise a doorbell and a remote computing device 204 such as a smartphone, laptop, tablet, or desktop computer. Some embodiments include obtaining the doorbell that comprises a camera, a speaker, a microphone, and a button, wherein the button is configurable to enable the first visitor to sound a chime.

FIG. 4 illustrates a camera's field of view 840. Methods can include configuring the camera of the doorbell such that the camera comprises a field of view 840, and using the camera of the doorbell to take a first image 842. The doorbell system can send the first image 842 from the doorbell to the remote computing device, which can comprise an electronic display 242 (shown in FIG. 2). Some methods include displaying the first image 842 on the electronic display 242 of the remote computing device, and prompting a user of the remote computing device to select a first detection zone 846 within the first image 842. The first detection zone 846 can comprise a portion of the first image 842. The first image 842 can comprise all or a portion of the camera's field of view 840.

In FIG. 4, the visitor 844 is located inside of the detection zone 846. An indication 850 of the visitor 844 is also located inside of the detection zone 846. The indication 850 can be any evidence or data that suggests the presence of the visitor 844. In FIG. 5, the visitor 844 and the indication 850 are located outside of the detection zone 846 in a second image 846. The first image 842 (shown in FIG. 4) and the second image 846 can show the same area (e.g., can include the same portion of the field of view 840). The detection zone 846 can consist of the same area (e.g., of an entryway) in both the first image 842 and the second image 846. In some embodiments, the first image 842 does not include a visitor 844 to help calibrate the system to a visitor-free state.

Some embodiments include using the camera of the doorbell to take a second image, analyzing the second image to detect a first indication of the first visitor, and determining that the first indication of the first visitor in the second image is located outside of the first detection zone. The doorbell system can then decide not to send an alert 232 (shown in FIG. 1) to the remote computing device in response to determining that the first indication of the first visitor in the second image is located outside of the first detection zone. The alert 232 can be configured to notify the remote computing device 204 (shown in FIG. 1) regarding a presence of the first visitor.

Analyzing the second image can include determining if there are signs of seeing the visitor in the second image. In some embodiments, the system looks for indications of motion in the image. In several embodiments, the system compares a baseline image (e.g., the first image) to the second image in order to determine if there are areas in the second image that include an object (e.g., a visitor) that was not present in the first image. Thus, some embodiments use computer vision to identify the presence of a visitor within the detection zone.

Several embodiments include using the camera of the doorbell to take a third image and analyzing the third image to detect a second indication of the first visitor. Methods can include determining that the second indication of the first visitor in the third image is located inside of the first detection zone, and then sending the alert to the remote computing device in response to determining that the second indication of the first visitor in the third image is located inside of the first detection zone. In some embodiments, the alert is not sent unless other conditions are met.

FIG. 6 illustrates a front view of a remote computing device 204 displaying a grid pattern 254 on an image 842. Some embodiments include displaying a grid pattern 254 on the first image 842 on the electronic display 242 of the remote computing device 204 such that the first image 842 is divided into sections 528 by lines 532 that cross each other. (Not all sections 528 and lines 532 are labeled in FIGS. 6-9 to increase the clarity of various features.)

The lines 532 can include horizontal lines and vertical lines that intersect at 90 degree angles. The lines can be straight, curved, and/or wavy. The sections can be equal in size and shape. The sections can be irregular and can vary in size. Methods can include preventing the sending of the alert to the remote computing device until after detecting an indication of a visitor in at least two, four, and/or eight of the sections. Methods can include preventing the sending of the alert to the remote computing device until after detecting an indication of a visitor in at least twenty percent and/or forty percent of the sections (e.g., of a detection zone).

FIG. 7 illustrates a subset 538 of the sections 528 that have been selected as part of a detection zone. Several methods include selecting the first detection zone within the first image 842 by the user touching at least a first subset 538 of the sections 528 on the electronic display 242 of the remote computing device 204. Touching the first subset 538 can cause the first subset 538 to be included in the first detection zone. The electronic display 242 can be a touchscreen of a computer such as a smartphone, tablet, or laptop. The user of the remote computing device 204 can swipe the touchscreen to select a detection zone.

Touching or clicking on each section is not necessary in some embodiments. Some methods include causing a second subset 542 of the sections to be included in the first detection zone in response to the first subset 538 comprising an outer perimeter that surrounds the second subset 542. For example, the user can swipe the touchscreen to form a closed shape. All sections at least partially located within the closed shape can be included in the first detection zone.

Some embodiments include two, three, four, and/or many detection zones, which can be independent, interdependent, separate, and/or overlapping. Detecting a visitor in a first detection zone can lead to immediately notifying the user of the remote computing device. Detecting a visitor in a second detection zone can include additional safeguards against false-positives.

Several embodiments include selecting the first detection zone by displaying the first image on the electronic display and then recording which areas (e.g., sections 528) of the first image the user indicates to include in the first detection zone by touching the electronic display. Some methods include calculating a percentage of the first detection zone that includes the second indication of the first visitor. The percentage can be a percentage of the area of the detection zone or can be a percentage of the sections. Methods can include sending the alert to the remote computing device in response to determining that the percentage of the detection zone exceeds a first threshold. The first threshold can be 10 percent or 30 percent.

Some methods include sending a picture of a visitor to the remote computing device, and then waiting to open audio and/or video communication between the visitor and the user of the remote computing device until after determining a percentage of the first detection zone that includes an indication of the visitor and calculating a time in which the indication of the visitor has been in the first detection zone. Embodiments can include opening the audio communication between the visitor and the user of the remote computing device in response to the percentage of the detection zone and the time. The percentage can be at least 10 percent and/or at least 25 percent. The time can be at least one second and/or at least four seconds.

Indications of the visitor can be motions indications. Motion indications can be identified by comparing a baseline image to another image. The baseline image can be taken when a visitor is not present. Other indications of the visitor can include presence indications (e.g., indications that at least a portion of the visitor is present in the section being analyzed).

Some embodiments include selecting the first detection zone by displaying the first image on the electronic display and then recording which areas of the first image the user indicates to include in the first detection zone by touching the electronic display. The remote computing device can prompt the user to select areas and/or sections to include in a detection zone. In some embodiments, the remote computing device does not display a grid on the calibration image, but the remote computing device prompts the user to select a portion of the image as the detection zone and/or prompts the user to select a portion of the image to exclude from the detection zone.

Several embodiments include calculating a percentage of the first detection zone that includes the second indication of the first visitor and/or calculating a time in which the second indication of the first visitor has been in the first detection zone. Methods can include sending the alert to the remote computing device in response to the percentage of the detection zone and the time.

The images used in several methods do not necessarily include the entire field of view of the camera of the doorbell. In some embodiments, the field of view comprises a portion, and the first image, the second image, and the third image consist of the portion of the field of view. Methods can further comprise selecting the portion of the field of view. In some embodiments, the images include the entire field of view of the camera.

The portion of the field of view can be consistent between the calibration image and subsequent images to help the system accurately analyze the images. In some methods, the first image, the second image, and the third image consist of at least a portion of the field of view, wherein the method further comprises analyzing the portion of the field of view.

Referring now To FIG. 3, although doorbells can be used anywhere, in some embodiments, the camera of the doorbell is configured to record a portion of an entryway 310, wherein the first image, the second image, and the third image show the portion of the entryway 310.

In some embodiments, the doorbell (e.g., 202) and the remote computing device 204 are not physically coupled. Methods can include wirelessly sending the first image from the doorbell to the remotely located computing device. Some embodiments include sending the first image directly from the doorbell to the remote computing device without an intermediary server (e.g., 206 in FIG. 1). This direct transmission can be via wires or can be wireless. Several embodiments include intermediary servers that enable the doorbell to communicate with the remote computing device via the Internet.

FIG. 8 illustrates a visitor 844 in a second image 852. The visitor is partially in the detection zone 846 (which was explained in the context of FIG. 7). The detection zone 846 was defined by selecting the subsets 538, 542 in FIG. 7. By analyzing the detection zone 846, the system can detect indications of the visitor 844. The system can ignore visitor indications located outside of the detection zone 846. Visitor indications can include motion and/or infrared signatures indicative of humans. In some embodiments, the system analyzes an image to identify shapes indicative of humans.

Methods for using a doorbell system to detect a first visitor can include obtaining the doorbell that comprises a camera and a button. The camera can be configured such that the camera has a field of view. Several embodiments include using the camera of the doorbell to take a first image to calibrate the doorbell system and sending the first image from the doorbell to the remote computing device. Some methods include displaying the first image on the electronic display of the remote computing device. Several embodiments include prompting a user of the remote computing device to select a first detection zone within the first image. The first detection zone can comprise at least a portion of the first image. Methods can include configuring the doorbell system to ignore a second visitor located within the field of view but located outside of the first detection zone.

The system can ignore a visitor by not sending an alert regarding the visitor to the remote computing device. In some embodiments, the system does not send an alert to the remote computing device in response to the presence of the visitor outside of the detection zone but inside of the field of view of the camera and/or inside of the image. Even when the system ignores a visitor, the system can record the visitor for future reference by the user. The user can then request to see visitors who were inside of the field of view but not shown via alerts (because they were ignored due to being located outside of the detection zone). Thus, the system can ignore the visitor in response to the presence of the visitor outside of the detection zone, but the system can later provide information regarding the visitor to the user in response to a user's request. Sending an alert can include sending a push notification to a smartphone.

Several methods include configuring the doorbell system to send a picture of a third visitor to the remote computing device in response to determining that the third visitor is located inside of the first detection zone as defined based on the first image. The first detection zone can be a two-dimensional zone rather than a three dimensional area of the physical world. Thus, the detection zone can be decoupled from proximity.

Some method embodiments include enabling audio and/or video communication between a visitor and the user of the remote computing device in response to detecting at least one indication of the visitor in at least two of the sections and/or in at least ten of the sections. In some embodiments, the sections with the detected indications must be adjacent to each other.

Some embodiments include selecting the first detection zone within the first image by prompting the user of the remote computing device to indicate a first area by touching the first area on the electronic display of the remote computing device; recording the first area; and excluding the first area from the first detection zone. Methods can include ignoring a visitor in response to the visitor being located in the first area.

Doorbells can comprise a motion sensor. Some embodiments include an infrared motion sensor. Methods can comprise ignoring the second visitor in response to disabling the motion sensor during a predetermined time period. The predetermined time period can be during certain hours of the day or night. The time period can be when the user is home or away from home (e.g., where the doorbell is mechanically coupled to the home). As used herein, “home” can include any type of stationary structure configured to shelter people (e.g., an office building).

Several embodiments include using a doorbell system to detect at least one visitor. Methods can include configuring the camera of the doorbell such that the camera comprises a field of view and using the camera of the doorbell to take a first image to calibrate the doorbell system by establishing a baseline of an entryway. The baseline can be used to define a state without any visitors. Methods can include sending the first image from the doorbell to the remote computing device and displaying the first image on an electronic display of the remote computing device.

Some methods include prompting a user of the remote computing device to select a first detection zone within the first image. The first detection zone can comprise a portion of the first image. The first detection zone can include a two-dimensional representation of an area in which the doorbell system is configured to respond to motion detection. Several embodiments include displaying a grid pattern on the first image on the electronic display of the remote computing device such that the first image is divided into at least ten sections by lines that cross each other. The system can be configured to identify the first detection zone within the first image by the user choosing at least a first subset of the sections on the electronic display of the remote computing device. Choosing the first subset can cause the first subset to be included in the first detection zone.

Several methods include configuring the doorbell system to ignore a second visitor located within the field of view but located outside of the first detection zone. Some embodiments include configuring the doorbell system to send a picture of a third visitor to the remote computing device in response to at least some of the following factors: (1) determining that the third visitor is located inside of the first detection zone as defined based on the first image, (2) determining that at least a predetermined percentage (e.g., thirty percent) of the first detection zone includes motion indicators, and (3) determining that the first detection zone has included the motion indicators for at least a predetermined amount of time (e.g., three seconds).

Some methods include automatically excluding an area from a detection zone. Automatic exclusion can occur without the user excluding a specific area (even if the user configures settings that later lead to automatic exclusions). In some embodiments, indications indicative of motorized vehicles (e.g., cars, trucks, vans) are automatically excluded from a detection zone. These automatic calibration innovations can take many forms. Several methods include automatically excluding an area from a detection zone in response to detecting an object (e.g., a motorized vehicle) moving through the first detection zone at more than twenty-five miles per hour. Some methods include automatically excluding an area in response to detecting an infrared signal indicative of a motorized vehicle.

Some embodiments include automatically excluding an area from the first detection zone in response to at least some of the following items: (1) detecting an indication of a visitor in a detection zone; (2) enabling audio communication between the doorbell and the remote computing device in response to detecting the indication of the visitor; and (3) using the doorbell to detect an absence of sound indicative of speaking. The area that is excluded can be the area in which the indication was detected.

FIG. 9 illustrates a doorbell system 528 that comprises a doorbell 506 (e.g., security system 202) and a remote computing device 204. The doorbell 506 has a camera assembly 208 and a doorbell button 212. Pressing the button 212 can cause the chime 302 (shown in FIG. 3) to sound (e.g., emit a “ding-dong” sound or another notification sound).

The camera assembly 208 is configured such that it has a field of view 840. The camera assembly 208 can be positioned such that the field of view 840 shows an entryway 878 (as illustrated in FIG. 9). The camera assembly 208 can take a first image 862, which can be all or part of the field of view 840. As used herein, phrases such as “take an image” are used in a very broad sense. A picture can be taken and then recorded on any of the items listed herein. Taking a picture can mean that a camera was used as at least one of several items used to capture an image. Taking a picture can be part of taking a video. Thus, an item that takes a video also takes a picture. The camera can be a digital video camera.

The doorbell system 528 can send the first image 862 to a remote computing device 204. The remote computing device 204 can display the first image 862 on an electronic display 242. The remote computing device 204 can prompt a user (of the remote computing device 204) to select at least one detection zone 846 within the first image 862. As illustrated in FIG. 9, the detection zone 846 is a portion of the first image 862. Multiple detection zones can overlap or can be separate.

The doorbell system 528 can send data regarding the selected detection zone 846 from the remote computing device 204 to the doorbell 506. The doorbell 506 can then focus on looking for visitors within the detection zone 846 and/or can ignore indications that are suggestive of a visitor if the indications are located outside of the detection zone 846.

In some embodiments, a computer (e.g., server 206 or computing device 204 in FIG. 1) that is located remotely from the doorbell 506 analyzes each image. Thus, the computer can apply the detection zone 846 to analyses of images from the doorbell 506 such that the doorbell 506 does not have to receive data regarding the detection zone 846. In some embodiments, the doorbell 506 sends an alert regarding a visitor to the remote computing device 204, but then the computing device 204 (and/or the server 206 in FIG. 1) blocks displaying the alert because the alert is from a visitor indication that was outside of the detection zone 846.

The camera assembly 208 can be used to take a second image 870. The detection zone 846 selected from the first image 862 can be positioned on the second image 870 such that the detection zone 846 represents the same area in front of the camera assembly 208 in both the first image 862 and the second image 870. For example, the detection zone 846 can focus a visitor detection analysis on the same portion of an entryway in images taken by the camera assembly subsequent to the camera assembly 208 taking the first image 862.

The doorbell system 528 can analyze the detection zone 846 of the second image 870. The doorbell system 528 can be used to analyze the second image 870 to determine whether a first indication of the visitor 844 is located inside of the detection zone 846. In FIG. 9, the doorbell system 528 determines that a first indication of the visitor 844 is located outside of the detection zone 846 (because the visitor 844 is located outside of the detection zone 846 in the second image 870). Then, the doorbell system 528 can decide not to send an alert and/or can block sending an alert to the remote computing device 204 in response to determining that the first indication of the visitor 844 is located outside of the detection zone 846.

The doorbell system 528 can be configured to notify the remote computing device 204 regarding a presence of the visitor 844 by sending an alert (e.g., a push notification) to the remote computing device 204. FIG. 9 illustrates the doorbell 506 sending an alert 232 to the remote computing device 204. The alert 232 can be sent directly from the doorbell 506 to the remote computing device 204. In some embodiments, the alert 232 is sent directly and wirelessly. In some embodiments, the alert 232 is sent via a server and/or via the Internet. The alert 232 can cause a push notification to appear on the user interface 240 of the computing device 204. In some embodiments, the alert 232 causes the remote computing device 204 to vibrate or “ring” to notify the user of the remote computing device 204 that a visitor may be present near the doorbell 202. The alert 232 can include a video of the visitor.

After the second image 870 was taken, the visitor 844 moved into the detection zone 846. The visitor 844 is located at least partially inside the detection zone 846 in the third image 874. The doorbell system 528 can analyze the third image 874 to detect an indication of the visitor 844. The doorbell system 528 can determine that an indication of the visitor 844 is located inside the detection zone 846.

Automatic Calibration

FIG. 10 illustrates a doorbell (e.g., security system 202) that has a field of view (“FOV”) 1000. The doorbell 202 can be part of a doorbell system (e.g., communication system 200) that includes a remote computing device 204, a server 206, and/or wireless communication 230 (shown in FIG. 1). The button 212 of the doorbell 202 can be configurable such that pressing the button 212 rings a chime 302 (shown in FIG. 3). The field of view 1000 can include a first portion 1004 and a second portion 1008.

Embodiments can include using doorbell 202 to detect a first object 1012 within the first portion 1004 of the field of view 1000; and/or determining that the button 212 was not pressed within a predetermined time after the doorbell detects the first object 1012 within the first portion 1004 of the field of view 1000. For example, the first object 1012 might be a car or a bird that is detected by the camera assembly 208 and/or by the motion detector 218. The car or bird will not press the button 212 like an actual visitor might do. As a result of the object's 1012 detection not being followed by a button 212 press (e.g., within 60 seconds), the doorbell system can become more skeptical of objects detected in the first portion 1004 of the field of view 1000. If the detected object 1012 had actually been a visitor (e.g., a person coming to the door), then the detection of the object 1012 likely would have been followed by the visitor pressing the doorbell button 212. This correlation between detecting remote objects and the doorbell system detecting a press of the doorbell button 212 can enable the doorbell system to automatically calibrate itself.

More specifically, the doorbell system can calibrate sensitivity in certain areas of the field of view 1000. For example, the first portion 1004 of the field of view 1000 might be of a road that passes in front of the building 300 (shown in FIG. 3) to which the doorbell 202 is attached. The movement on the road and/or the presence of new objects on the road could lead to many false positives. For example, the doorbell 202 could detect a car on the road and then automatically send an alert regarding a “visitor” to the remote computing device 204 (shown in FIG. 1). The user of the remote computing device 204 could then be irritated that the passing car is not actually a visitor, and thus, the alert inappropriately distracted the user. The doorbell system can reduce the sensitivity of the detection system in the first portion 1004 to reduce false positives (e.g., due to passing cars). In some cases, the sensitivity of the detection system is reduced so much that the system excludes the first portion of the field of view from causing an alert configured to notify the remote computing device regarding a presence of a “visitor” (e.g., when the suspected “visitor” is a passing car and not a visiting person).

The field of view 1000 can include a second portion 1008 that can be commonly associated with detecting indications of real visitors. For example, the system can detect an object 1016 in the second portion 1008. This detection can be followed by the object 1016 (i.e., a real visitor) triggering the doorbell button 212 (by pressing the button 212). This correlation can increase the probability of another object 1020 detected within the second portion 1008 resulting in the system sending the alert to the remote computing device 204 (shown in FIG. 1) even if the object 1020 does not ring the doorbell button 212 or before the object 1020 rings the doorbell button 212.

Embodiments can include many detection areas (such as the first portion 1004 and the second portion 1008). For example, the sections 528 in FIG. 6 can each be individual detection areas that are individually calibrated based on doorbell button triggering data that is individually associated with the detection areas. Some of the sections 528 can be excluded from causing an alert if motion, image indications, and/or infrared data detected in those sections is not typically correlated with doorbell button triggering.

FIG. 11 illustrates a visitor 844 located within the second portion 1008 of the field of view 1000. The visitor detection system 1024 can be configured to detect the visitor 844. The visitor detection system 1024 can comprise at least one of a camera 208, a motion detector 218, and/or an infrared detector 222. The visitor detection system 1024 is configured to detect a first indication 1028 suggestive of the visitor 844. In this example, the first indication 1028 is misleading because, although it is suggestive of a visitor, the indication 1028 was caused by something other than a visitor. For example, the first indication 1028 might have been caused by a passing car, an animal, or wind blowing a garbage container over. The system can realize that indications in the first portion 1004 of the field of view 1000 are unreliable if indications in the first portion 1004 of the field of view are not typically followed by the doorbell button 212 being triggered.

An indication can be suggestive of the visitor if the indication is of a type that may indicate a visitor (even if the indication can sometimes result in false positives). For example, the indication can be a motion indication, but at times, motion indications may result from moving cars, pets, and plants. As a result, a motion indication may not actually indicate a visitor even though the indication suggests that a visitor may be present.

An infrared signature that seems to indicate that a visitor is present can be a type of indication. The infrared signature may be of a shape and/or temperature that suggests the infrared signature is from a visitor (i.e., a person). In many cases, infrared signatures suggestive of visitors are actually from visitors, but in some cases, infrared signatures suggestive of visitors may be misleading (and not actually be from visitors).

A shape in an image taken by a camera may be an indication suggestive of a visitor. For example, the shape can be of a size or geometry that suggests the shape represents at least a portion of a visitor. In some cases, shapes suggestive of a visitor may not actually be from a visitor.

Doorbell triggering (e.g., pressing) data can be used to substantiate suggestive indicators. Thus, embodiments can grow more skeptical of indicators if they are not followed by, for example, a visitor pressing the doorbell button. Certain areas of the field of view can be discounted or ignored altogether if indicators associated with the certain areas are not followed by a visitor pressing the doorbell button.

Embodiments can grow more confident of indicators if they are followed by a visitor pressing the doorbell button. In some embodiments, all areas of the field of view are configured to trigger an alert regarding the visitor until indications associated with certain areas are not followed by visitors pressing the button. Then, the system can ignore indications in those areas (to reduce the number of false positives).

Some embodiments include using the visitor detection system to detect the first indication suggestive of the first visitor within a first portion of the field of view and determining that the first indication detected within the first portion of the field of view is not associated with a triggering of the button.

Several methods can be used to determine if an indication is associated with a triggering of the button. In some embodiments, the system waits for a predetermined amount of time (e.g., 60 seconds or less) after detecting the indication to determine if the doorbell button is pressed. If the button is not pressed within the predetermined amount of time, then the indication is not associated with the triggering of the button.

The system can be configured to determine if the object that resulted in the indication suggestive of the visitor later pressed the doorbell button. If the object pressed the doorbell button, then the indication was associated with the triggering of the button. If the object did not press the doorbell button, then the object was not associated with the triggering of the button. This approach enables the system to calibrate its remote detection capabilities based on doorbell button data. Then, the system can more accurately determine if an indication is actually a visitor (to reduce false positives). As a result, the system can more reliably send an alert about a later visitor even if the visitor does not press the button.

A visitor can trigger the doorbell button in several ways. In many embodiments, the visitor triggers the doorbell button by pressing the doorbell button (e.g., to make the chime “ring”). Some embodiments include a button that can be triggered without pressing the button. For example, the visitor can trigger the button by touching the button. Some embodiments include “contactless” switches (e.g., Hall effect sensors) that enable triggering the button without actually touching the button.

Several embodiments include using the visitor detection system to detect a second indication suggestive of a second visitor within the first portion of the field of view and excluding the first portion of the field of view from causing an alert configured to notify the remote computing device regarding a presence of the second visitor. The excluding can be at least partially in response to determining that the first indication detected within the first portion of the field of view is not associated with the triggering of the button. The excluding prevents the second indication from causing the alert.

In some embodiments, this exclusion can create zones within the field of view that will not cause the system to send the alert even though the system detects an indication suggestive of a visitor in the excluded zones. This exclusion often will not prevent all indications from causing an alert if the indications are detected in non-excluded zones.

Several embodiments include using the visitor detection system to detect a third indication suggestive of the second visitor within a second portion of the field of view and then sending the alert in response to detecting the third indication within the second portion. The first indication can be a first motion indication, the second indication can be a second motion indication, and the third indication can be a third motion indication.

In some embodiments, the doorbell system determines that the first indication detected within the first portion of the field of view is not associated with the triggering of the button by determining that the button was not triggered within 60 seconds after detecting the first indication. 60 seconds can be a good timeframe because visitors approaching a doorbell will typically ring the doorbell within 60 seconds. If the item that caused the indication has not pressed the doorbell button within 60 seconds of being detected, then the item might not actually be a visitor and might be a passing car, a pet, a wind-blown tree branch, or another misleading item.

Of course, there will be times when an actual visitor does not press the doorbell button. For example, a person might choose to knock on the door instead of ringing the doorbell button. Thus, some embodiments include listening for sounds 1030 indicative of a visitor. Sounds 1030 indicative of a visitor include talking and knocking. Some embodiments are similar to other embodiments described herein except that the embodiments determine whether an indication detected within the first portion of the field of view is associated with sounds 1030 indicative of a visitor.

As a result of there being times when an actual visitor does not press the doorbell button, some embodiments do not immediately exclude a portion of the field of view from causing an alert, but instead, rely on data from many visitors and/or adjust the sensitivity of the visitor detector in the portion of the field of view.

FIG. 11 illustrates an indication 1032 that resulted from a visitor 844 approaching the doorbell 202. The doorbell system can detect the indication 1032 based on detecting the infrared signature of the visitor 844, detecting the motion of the visitor 844, and/or comparing a baseline image to a second image of the field of view 1000 and then determining that the indication 1032 is present in the second image but not in the baseline image.

Infrared signature is used to describe the appearance of objects to infrared sensors. Infrared signatures can be influenced by a wide range of factors (e.g., object shape, temperature, background). As used herein, infrared signature is used in a broad sense to describe detecting an object based on the infrared indication of that object.

FIG. 12 illustrates an infrared signature 1036 of the visitor 844 shown in FIG. 11. The infrared detector 222 can detect the infrared signature 1036. Although the infrared signature 1036 was caused by a real visitor 844, many objects that are not visitors can cause infrared signatures. As a result, many embodiments use doorbell button 212 data to calibrate the visitor detection system 1024. Infrared signatures that are not associated (e.g., followed) by a press of the doorbell button 212 may be categorized as unreliable indications of a visitor. Portions of the field of view 1000 that commonly cause unreliable indications may be precluded from causing an alert to be sent to the remote computing device 204 (shown in FIG. 1). For example, cars passing in the first portion 1004 of the field of view 1000 may have an infrared signature that the doorbell system could mistake for a visitor (e.g., a person approaching the doorbell). If so, the system can become more reliable (and better calibrated) by ignoring infrared signatures in the first portion 1004 of the field of view 1000.

In some embodiments, the visitor detection system comprises the infrared detector, wherein using the visitor detection system to detect the first indication within the first portion of the field of view comprises detecting a first infrared signature within the first portion. Methods can include reducing a first sensitivity of the visitor detection system within the first portion in response to determining that the button was not triggered within 60 seconds after detecting the first indication. Reducing the first sensitivity can reduce a first probability of causing a first alert configured to notify the remote computing device regarding a presence of a second visitor in response to detecting a second indication suggestive of the second visitor within the first portion of the field of view.

In several embodiments, the infrared detector comprises a first infrared sensor and a second infrared sensor. The doorbell can comprise a wall that separates the first infrared sensor from the second infrared sensor such that the first infrared sensor is configured to detect the first infrared signature within the first portion and the second infrared sensor is configured to detect a second infrared signature within a second portion of the field of view.

Some embodiments include using the infrared detector to detect a third indication suggestive of a third visitor within a second portion of the field of view; and/or increasing a second sensitivity of the visitor detection system within the second portion in response to determining that the button was triggered within 60 seconds after detecting the third indication. Increasing the second sensitivity can increase a second probability of causing a second alert configured to notify the remote computing device regarding the presence of the third visitor in response to detecting the third indication within the second portion of the field of view.

FIG. 13 illustrates an embodiment with motion indications 1038, 1040. The motion detector 218 can detect the motion indications 1038, 1040. The first motion indication 1038 can be from a passing car traveling at 35 miles per hour. The second indication 1040 can be from the visitor 844 approaching a door located in the same entryway as the doorbell 202. The visitor 844 can be moving at less than 5 miles per hour, which is typical of people as they approach doors. Cars tend to move much faster than people walking towards doorbells, so a speed threshold can be a useful way for the doorbell system to distinguish between people (which are typically true positives) and cars (which are typically false positives).

If the first portion 1004 of the field of view 1000 typically results in false positives (e.g., based on objects that are moving too fast and/or based on detecting objects that then do not ring the doorbell), then the first portion 1004 can be precluded from causing alerts. If the second portion 1008 of the field of view 1000 typically results in true positives (e.g., based on objects that are moving at a speed below the predetermined threshold and/or based on detecting objects that then ring the doorbell), then the doorbell system can increase its sensitivity to motion indicators in the second portion 1008 of the field of view 1000.

Speed is one of many factors that can help distinguish between misleading motion and motion that is from an actual visitor. People tend to approach doorbells at less than 5 miles per hour. In contrast, cars tend to drive over 25 miles per hour and often drive over 35 miles per hour. Excluding motion that is over 5 miles per hour can help improve the accuracy of the doorbell system (by screening out motions that are too fast to likely be from a visitor).

Several methods include detecting a speed of the first motion; and/or excluding the first motion from causing the alert configured to notify the remote computing device regarding the presence of the first visitor. The excluding can be at least partially in response to the speed being greater than a predetermined threshold. The predetermined threshold can be at least 5 miles per hour and can be less than 35 miles per hour. A predetermined threshold of 15 miles per hour provides a very reliable dividing line between people walking up to a doorbell and cars driving in front of the doorbell. Several embodiments include a predetermined threshold of at least 15 miles per hour.

In some embodiments, the visitor detection system comprises a motion detector. Using the visitor detection system to detect the first indication within the first portion of the field of view can comprise detecting a first motion within the first portion. Embodiments can include reducing a first sensitivity of the visitor detection system within the first portion in response to determining that the button was not triggered within a predetermined time (e.g., 60 seconds, 30 seconds, 15 seconds) after detecting the first indication. Reducing the first sensitivity can reduce a first probability of causing an alert configured to notify the remote computing device regarding a presence of a second visitor in response to detecting a second indication suggestive of the second visitor within the first portion of the field of view.

Several embodiments include using the visitor detection system to detect a second motion within a second portion of the field of view; and/or increasing a second sensitivity of the visitor detection system within the second portion in response to determining that the button was triggered within 60 seconds after detecting the second motion. Increasing the second sensitivity can increase a second probability of causing the alert configured to notify the remote computing device regarding the presence of the second visitor in response to detecting the second motion within the second portion of the field of view.

Some embodiments include dividing the field of view into the first portion and the second portion such that the doorbell system is configured to distinguish between the first motion detected in the first portion and the second motion detected in the second portion. A wall (e.g., a plastic blade) can be used to divide the field of view. In some embodiments, the field of view is divided with software (e.g., rather than being physically divided by a wall).

Several embodiments for using a doorbell to detect visitors include obtaining the doorbell system that comprises a motion detector and a button; configuring the doorbell system such that the motion detector comprises a field of view; detecting a first motion within a first portion of the field of view; determining that the button was not triggered within 60 seconds after detecting the first motion within the first portion of the field of view; and/or excluding the first portion of the field of view from causing an alert configured to notify the remote computing device regarding a presence of the first visitor. The excluding can be at least partially in response to determining that the button was not triggered within 60 seconds after detecting the first motion within the first portion of the field of view.

Some embodiments include detecting a second motion within a second portion of the field of view; determining that the button was triggered within 60 seconds after detecting the second motion within the second portion of the field of view; and/or configuring the doorbell system to automatically send the alert regarding a third motion detected in the second portion of the field of view at least partially in response to determining that the button was triggered within 60 seconds after detecting the second motion within the second portion of the field of view.

Several embodiments include detecting the third motion within the second portion of the field of view; and/or automatically sending the alert to the remote computing device regarding the presence of a visitor in response to detecting the third motion within the second portion of the field of view. Methods can include automatically initiating the sending of the alert to the remote computing device regarding the presence of the first visitor prior to the first visitor pressing the button.

FIG. 14 illustrates a baseline image 1044 of the field of view 1000. FIG. 15 illustrates a second image 1048 of the field of view 1000. Referring now to FIGS. 14 and 15, the camera assembly 208 can take the baseline image 1044 and the second image 1048. The doorbell system can compare the baseline image 1044 to the second image 1048 to detect an indication 1052 of the visitor 844. The system can then determine that the indication 1052 is present in the second image 1048 but not in the baseline image 1048.

In several embodiments, the visitor detection system comprises a camera, and using the visitor detection system to detect the first indication within the first portion of the field of view comprises using the camera to take a first image. Then, the doorbell system can analyze the first image to detect the first indication. Embodiments can include reducing a first sensitivity of the visitor detection system within the first portion in response to determining that the button was not triggered within a predetermined time after detecting the first indication. Reducing the first sensitivity can reduce a first probability of causing a first alert configured to notify the remote computing device regarding a presence of a second visitor in response to detecting a second indication suggestive of the second visitor within the first portion of the field of view.

Some embodiments include using the camera to take a second image. Then, the doorbell system can analyze the second image to detect a third indication suggestive of a third visitor within a second portion of the field of view. Methods can include increasing a second sensitivity of the visitor detection system within the second portion in response to determining that the button was triggered within 60 seconds after detecting the third indication by analyzing the second image. Increasing the second sensitivity can increase a second probability of causing a second alert configured to notify the remote computing device regarding the presence of the third visitor in response to detecting the third indication within the second portion of the field of view.

Several embodiments include using a doorbell system to detect a first visitor. The doorbell system can comprise a doorbell and a remote computing device. Methods can include obtaining the doorbell that comprises a camera and a button. The button can be configurable to enable the first visitor to sound a chime. Methods can also include configuring the doorbell system such that the camera comprises a field of view; using the camera of the doorbell to take a baseline image to calibrate the doorbell system by establishing a baseline of at least a part of the field of view; using the camera of the doorbell to take a second image of at least the part of the field of view; determining that a first object is present in the second image, but not in the baseline image; associating the first object with a first portion of the field of view; determining that the button was not triggered within 60 seconds after determining that the first object is present in the second image, but not in the baseline image; and/or excluding the first portion of the field of view from causing an alert configured to notify the remote computing device regarding a presence of the first visitor. The excluding can be at least partially in response to determining that the button was not triggered within 60 seconds after determining that the first object is present in the second image, but not in the baseline image.

Associating the first object with the first portion of the field of view can include correlating the first object with a location within the field of view. For example, the system can know where in the field of view the first object was detected. This relative location information can be helpful so the system can determine which areas of the field of view are causing misleading indications (e.g., as implied by an indication not being followed by a triggering of the doorbell button within 60 seconds of the system detecting the indication).

Many factors and methods can be used to exclude a portion of the field of view from causing an alert. For example, sound data and button data can be combined to exclude the portion of the field of view. In some embodiments, many button press data points are used to eventually exclude a portion of the field of view. Thus, excluding can be at least partially in response to determining that the button was not triggered within 60 seconds after determining that the first object is present in the second image, but not in the baseline image, even though other factors and methods are ultimately used in the full exclusion decision.

Several embodiments include using the camera of the doorbell to take a third image of at least the part of the field of view; determining that a second object is present in the third image, but not in the baseline image; associating the second object with a second portion of the field of view; determining that the button was triggered within 60 seconds after determining that the second object is present in the third image, but not in the baseline image; and/or configuring the doorbell system to automatically send the alert regarding a third object detected in the second portion of the field of view at least partially in response to determining that the button was triggered within 60 seconds after determining that the second object is present in the third image, but not in the baseline image.

Some embodiments include using the camera of the doorbell to take a fourth image of at least the part of the field of view; determining that the third object is present in the fourth image, but not in the baseline image; associating the third object with the second portion of the field of view; and/or automatically sending the alert to the remote computing device regarding the presence of a visitor.

Several embodiments include automatically initiating the sending of the alert to the remote computing device regarding the presence of the first visitor prior to the first visitor pressing the button. Initiating the sending of the alert does not necessarily mean that the alert has arrived at the remote computing device.

The baseline image can comprise several images. In some embodiments, the baseline image is actually a collection of images taken at different times. Thus, a first image can be the baseline image for a second image, and the second image can be the baseline image for a third image.

FIG. 16 illustrates an embodiment in which a wall 1060 divides the field of view 1000 into a first portion 1064 and a second portion 1068. The infrared detector 222 and/or the motion detector 218 (shown in FIG. 12) can include a first sensor 1070 and a second sensor 1074. The sensors 1070, 1074 can be infrared sensors and/or motion sensors.

In several embodiments, the infrared detector 222 comprises a first infrared sensor and a second infrared sensor. The doorbell 202 (shown in FIG. 12) can be configured such that the wall 1060 separates the first infrared sensor from the second infrared sensor such that the first infrared sensor is configured to detect the first infrared signature within the first portion and the second infrared sensor is configured to detect a second infrared signature within a second portion of the field of view.

The wall 1060 can be configured to divide the field of view 1000 into portions 1064, 1068 such that the doorbell system can distinguish between motions in different portions 1064, 1068. For example, the wall 1060 can be configured to prevent a second sensor 1074 from detecting a motion that the first sensor 1070 can detect (e.g., because the wall 1060 can “hide” the motion from the second sensor 1074).
